Description

A kind of fluoroplastics heat exchanger frame spray ash handling equipment

Technical field

This utility model belongs to energy-saving and environmental protection and field of heat exchange, relates to a kind of flue gas heat-exchange unit spray ash handling equipment, particularly to a kind of fluoroplastics heat exchanger frame spray ash handling equipment.

Background technology

The tube-sheet heat exchanger reclaimed for residual heat from boiler fume, it is typically necessary solution removing and is attached to the problem of dust on heat exchanger tube, the most in recent years the teflon heat exchanger occurred, owing to being limited by conditions such as heat exchanger tube spacing, material, temperature, the method that have employed cleaning showers ash disposal.But, known spray equipment in field at present, is separately provided a spray system (detailed construction is with reference to adnexa: background technology accompanying drawing) owing to using in the outer side of heat exchanger frame, there is the water yield, hydraulic pressure skewness, ash disposal inefficiency, the shortcoming that water consumption is big.This utility model efficiently solves the problem that existing spray equipment exists, and uses this utility model to can reach uniform spraying, and dedusting effect is good, the most also has and saves equipment cost and save the additional effect taking up an area space.

Utility model content

It is big to there is occupation of land space in existing teflon heat exchanger spray mode, investment height, the defects such as non-uniform spraying, dedusting effect are the best.The utility model proposes a kind of small investment, efficiency is high, more economize on water, reliable and stable fluoroplastics heat exchanger sprays ash handling equipment.

Technical scheme is as follows:

1, four stay tubes fluid hose as shower water of heat exchanger bearing frame, framework supervisor, arm conveying spray medium while playing the effect that structure supports are utilized.

2, heat exchanger tube pass part is divided into four essentially identical regions of size.

3, four main structure pipes (hereinafter referred to as supervisor) of heat exchanger bearing frame corner respectively with aforementioned four region arm UNICOMs；Arm layered arrangement, with shower UNICOM；The shower spray scope area of coverage all heat exchanger tubes tube bank.

4, according to operating mode to spray the hydraulic pressure of ash disposal system, discharge, the requirement of spray frequency, select be suitable for pipeline material, diameter, wall thickness, rate-of flow；The most discontinuously spray by automatically controlling enforcement.

This utility model optimizes fluoroplastics heat exchanger spray dedusting effect, has an advantage in that:

1, using the heat exchanger of this utility model spray ash handling equipment, the heat exchanger of its volume ratio conventional spraying device reduces about 15%, reduces the occupation of land space of heat exchanger.

2, owing to taking heat exchanger tube pass subregion to spray successively, each region spray rate-of flow, pressure is made to tend to uniform；Eliminate spray blind area or dead angle；Substantially increase spray dedusting effect.

3, saving spray-water, water consumption has only to about the 30% of conventional spraying device.Saving spray water system electricity consumption, pump power has only to about the 30% of conventional spraying device.

4, owing to being substantially improved dedusting effect, be conducive to improving the heat exchange efficiency of heat exchanger.

Detailed description of the invention

Utilize four supporting steel pipes, four supervisors as spray system of heat exchanger block supports framework, below in conjunction with accompanying drawing, this utility model detailed description of the invention be described further:

1, heat exchanger tube pass part is divided into from top to bottom four suitable regions of size (as shown in Figure 1).2, supervisor's (1-1), (1-2), (1-3), (1-4) (as shown in Figure 2), it is welded to form heat exchanger support frame (as shown in Figure 1, Figure 3) with arm (2-1), (2-2), (2-3), (2-4).3, supervisor (1-1) and arm (2-1) tube chamber UNICOM, supervisor (1-2) and arm (2-2) tube chamber UNICOM, supervisor (1-3) and arm (2-3) tube chamber UNICOM, supervisor (1-4) and arm (2-4) tube chamber UNICOM；One end of shower (3) and each arm tube chamber UNICOM, the other end is fixed with opposite arm；Form four the independent spray systems (as shown in Figure 1, Figure 3) corresponding with four tube side spray districts.4, supervisor (1-1), supervisor (1-2), supervisor (1-3), supervisor's (1-4) flange are connected with four external fluid delivery conduit roads respectively, and from top to bottom or the most discontinuously spray or pulse spray to utilize automaton to realize four spray districts.
